The two-part resin cures in 2 hours. It is also compatible with almost any paint system or gel coat. Bondo® All-Purpose Fiberglass Bondo® Fiberglass Resin Liquid Hardener is included with the resin.

Waterproof for Added Versatility
Made with the same resin used to build many boats, Bondo® All-Purpose Fiberglass Resin is 100% waterproof for a versatile range of projects such as repairing tubs, showers, sinks, pools, hot tubs and boats. Replacing damaged tubs or shower units or paying someone to repair your boat can be expensive. This resin lets you make durable waterproof repairs yourself, in very little time and at much less cost.

Structurally Strong through a Chemical Bond
When used with Bondo® Fiberglass Cloth or Mat, Bondo® All-Purpose Fiberglass Resin makes for extremely strong and durable repair in projects large and small. When the resin and the included liquid hardener are mixed, a reaction occurs which allows the resin to chemically bond to the surface you are repairing.

Recommended Applications:

  • Sink, tub, and shower rebuilds
  • Repairing hot tubs and pools
  • Sealing concrete or wood
  • Resurfacing boats and other water craft
  • Rust outs in metal
